From AAA to large D-cells

The charger has four charging slots. The list of supported sizes includes AA, AAA, C, D, and 18650, so it doesn’t stop at common AA and AAA batteries. According to the parameters, it handles NiMH, NiCd, and Li-Ion batteries. The range of supported cells is precisely why you should consider it instead of a charger designed only for AA batteries.

An LCD display is used for charging control. Discharging, testing, and recovery modes are available; additionally, the seller mentions a 0V activation function for long-unused batteries. For older battery stocks, this feature might be more interesting than just charging. However, recovery cannot be taken as a guarantee of saving every old cell.
